공업구조의 고도화 정책으로 산업구조는 중화학공업 중심으로 전환되여 왔고, 이들 공장들은 연안지역에 새로이 집중 배치 되었다. 그러나, 이러한 연안중심의 공업단지조성은 인구의 밀집현상을 초래하게 되었으며 이로 인하여, 발생되는 오염물질들은 제대로 처리되지 않은채 직·간접적으로 해양에 유입되여 해양자원은 물론 자연환경에도 막대한 손실을 가져오고 있다. 본 연구에서는 최근 조성 되여지고 있는 인천 남동공단을 대상으로 해양환경기준을 유지하기 위하여 주하천인 승기천의 오염부하량을 산정, 종말처리장의 배출수 농도를 예측하였다. 조사된 승기천의 현재 COD부하량이 2,651.7㎏/day 유량이 88,500㎥/day이고, 공단이 조성된 후 COD부하량은 18,317.7㎏/day 유량은 187,300 ㎥/day 이다. 해역의 농도가 COD로써 1.3 ㎎/ℓ일때 종말처리장의 배출수 농도는 COD로써 23 ㎎/ℓ이하, 효율 76.5% 이상을 유지시켜야 할 것으로 사료된다.

The industrial structure has converted to heavy chemical industry outing to the hightechnical policy of a industrial structure and these factories were arranged intensively in the district along the coast but this formation of a coastal industrial complex brought about a population concentration. Therefore, the producing pollutants were flowed into a directly or indirectly without a perfect treatment these facts brought about a great loss in resources of the sea and destruction of natural environment In present work, in order to keep the standard of marine environment around the Namdong industrial complex being built up recently in Inchen and to reduced the quality of the discharged water in the last treatment place, the pollution load factor of Sungi river (main river) has been estimated. The present COD load factor and the flux of the Sungi river show the values of 2,651.3 kg/day and 88,500 m3/day respectively. After the industrial complex were formed, the COD load is 18,317.7 kg/day and the flux is 187,300 m3/day. The discharge water concentration of is the value of 23 mg/1 as COD and the efficiency of discharge water is over 76.5 percent, assuming the quality of sea water is 1.3 mg/l as COD.
